2013-07-15hw/dma/omap_dma: Fix bugs with DMA requests above 32Peter Maydell
The drqbmp field of struct soc_dma_s is a uint64_t; however several places in the code attempt to set bits in it using "(1 << drq)", which will fail if drq is large enough that the 1 bit gets shifted off the top of a 32 bit integer. Change these to "(1ULL << drq)" so that the promotion to 64 bit happens before the shift rather than afterwards.

2013-06-20dma: eliminate DMAContextPaolo Bonzini

2013-06-10xilinx_axidma: Do not set DMA .notify to NULL after notifyWendy Liang
If a stream notify function is not ready, it may re-populate the notify call- back to indicate it should be re-polled later. This break in this usage, as immediately following the notify() call, .notify is set to NULL. reverse the ordering of the notify call and NULL assignment accordingly.

2013-04-20qdev: Drop taddr propertiesPeter Maydell
Drop all the infrastructure for taddr properties (ie ones which are 'hwaddr' sized). These are now unused, and any further desired use would be rather questionable since device properties shouldn't generally depend on a type that is conceptually variable based on the target CPU. 32 or 64 bit integer properties should be used instead as appropriate for the specific device.

2013-04-16stream: Remove app argument hackPeter Crosthwaite
The uint32_t *app argument doesn't exist in real hardware. It was a hack in xilinx_axidma/enet to fake the (secondary) control stream connection. Removed the argument and added the second stream to axienet/dma. Signed-off-by: Peter Crosthwaite <peter.crosthwaite@xilinx.com> Signed-off-by: Edgar E. Iglesias <edgar.iglesias@gmail.com>
2013-04-16xilinx_axienet/dma: Implement rx path flow controlPeter Crosthwaite
Implement flow control for the RX data path from xilinx_axienet->xilinx_axidma. On short return from axidma, then ethernet sets up the notify callback to resume transfer from where it left off. This also allows the ethernet to track whether there is an in progress transaction and return false from ethernet can_receive() as appropriate. If the DMA backs up or is disabled it waits for enablement. When the rx stream IO region is touched, the can_push() notify function is called if set.

2013-04-16stream: Add flow control APIPeter Crosthwaite
Add basic flow control to stream. A stream slave may return short, indicating that it is not capable of accepting any more data at the present time. Polling or a callback can be used via the can_push() function to determine when the slave can receive again. Signed-off-by: Peter Crosthwaite <peter.crosthwaite@xilinx.com> Signed-off-by: Edgar E.

2013-04-16xilinx_axidma: Create Proxy object for streamPeter Crosthwaite
Create a separate child object to proxy the stream slave connection. This is setup for future work where a second stream slave connection is needed. The new child object is created at qdev init time and is linked back to the parent (the ethernet device itself) automatically. Stream slave masters differentiate which slave connection they are connected to by linking to the proxy object rather than the parent.
